Hi! This is my first english fanfic! I'm from Spain so sorry for any vocab/grammar mistakes. Correct me if you catch them. This idea wouldn't leave my head. I don't know how long would it be or what would come out of it, but I hope you enjoy it! I am thinking of uploading a chapter every week so... leave some reviews!

She couldn't sleep and Castle's soft snoring wasn't helping at all. Pregnant. She was pregnant and she couldn't sleep. It was a good thing, wasn't it? Her marriage... her husband... a baby. It seemed to be the way it should, like the natural course of things. But she kept thinking what if she was a terrible mom? What if she couldn't see her baby because of her job? What if...? She couldn't stop thinking of the possibilities of everything that could go wrong... and that made her not able to sleep.

She turned around, looking to Castle, and had to smile. He looked so peaceful, a bit sweaty because of the sleep but still kind of adorable. Kate slightly touched his face, softly, trying not to wake him up. It comforted her to feel their connection, the way he would lean towards her touch. She moved closer to him, breathing his scent, and closed her eyes. It had been 4 months. Four incredibly short months since she found out they were having a baby. Four months in which Castle was nothing else but the perfect husband, nearly in an annoying way. He would know all of this crazy facts about pregnancies, would prepare healthy dinner every night, give her massages (oh, god, she loves his massages) and wouldn't let her drink coffee or wine. No coffee. That made her be a little bit cranky. All right, not just a little bit. Very. She was cranky mostly all the time. But he didn't seem to care. That was the only reason she thought that could work. He was with her. He would help her be a good mom. He would take care of their child whenever she had to work. He would make things so much easier.

She tried counting sheep. That could work, right? Castle's breathing helped her to keep the rhythm. She was imagining sheep number 40 jumping over a bench when she felt something inside her. Her heart started pumping harder. Was everything okay? She thought that she had to relax. Surely it was nothing, just a... oh. Realization hit her in that second. Just a movement. Her baby had just kicked her for the first time.

"Castle" she shook him softly to wake him up "Hey, babe, wake up."

"I hope you are looking for kinky sex because it's kind of late" he moved with his eyes still closed until his face was hiding in the crook of her neck.

"Give me your hand"

"Wow, Beckett, you really need me..."

"Shut up, Castle. The baby just kicked. I though you would like to feel it if it happened again" He sat on the bed, startled and a bit disoriented. Kate couldn't help but laugh at his expression. She gave him a soft kiss and guided his hand over her stomach.

"Are you sure? Maybe it was just...

"Castle, I'm sure. He kicked. Our baby." Castle lay down again, his head over Kate's stomach.

"Hey, munchkin. I'm dada. Can you kick again for me? I'm sorry that I was sleeping, but being around mommy this days has been exhausting." he smiled and kiss her belly when she punched him "But momma is a softie. She woke me up so that I could feel it too. Move again, baby."

They stayed like that. In that same position until they thought nothing was going to happen. But then there it was. Their baby kicked her. Hard. She even bend a little bit because of it. But it was worth it just to she Castle's face. He looked like a child himself. A child opening Christmas presents.

"That was a really good one, munchkin. Now go to sleep. Mommy is tired too." he murmured to her belly." That was awesome"

"I know, right? Castle, do you think... do you think I am going to be good for our baby? I mean, I love him... or her, you know? But there are sometimes when I think that I shouldn't be doing this. Not because of you, or us, but because of me. What if I am a terrible influence? What if all my baggage affects the baby? What if..?"

"Hey, hey" He shut her up with a kiss and pull her into his embrace "you already are a terrific mother. Don't think I haven't heard you talking to the baby when you think I'm asleep. You are strong and loving and I'm sure that whenever the pregnancy comes to an end you will be in a really good mood." She hit him again but he felt her smile on his chest " Just joking. You are great, Kate. We are going to be great. The three of us, I promise. Now, can we go back to sleep?"

"Actually... I thought you said something about kinky sex?" she sit on her lap and kissed his neck, softly. Tempting.

"You pervert..."

After that, she didn't need to count sheep anymore.
